FRANKI PILE PDF

The Franki pile is a driven, cast-in-situ concrete displacement pile with an enlarged base in dry concrete and a cylindrical shaft. Dulce Simoes 7th December Piling. It takes more than the highest levels of ground engineering expertise and experience to be Keller’s Franki Africa. FRANKI DRIVEN CAST-IN-SITU PILES (DCIS). The Franki pile has been used extensively throughout Southern Africa for over 65 years and is still today one of.

Franki Piles is a driven, enlarged base, cast in-situ pile that can be farnki in practically all soil conditions. Geotechnical engineering Civil engineering Foundations buildings and structures. It is a cast-in-situ concrete pile with an enlarged base and a cylindrical shaft which, due to its powerful driving method during installation, can penetrate stiff soils and reach large depths.

Franki pile

The Franki pile process has undergone several reformations since it was conceived. Due to the compression of the concrete plug, a water-tight bottom framki is created which prevents soil or water from entering the casing. It is interesting that in both the below marine projects, one of the common themes is great teamwork ….

Among the important skills required to wear this crown, especially in these times of challenging economic conditions, are the abilities to franji original … Read More. In that case, a pre-fabricated shaft steel or concrete is installed after the expanded base has been constructed in the ordinary way.

Soil Mechanics and Foundationsp. The Yacht Club, a … Read More. Established in and Executed plenty big piling projects in Iraq. This operation causes compression of the soil by piel displacement. The expanded base of the pile is then formed by adding as much dry concrete as necessary to achieve a pre-determined “driving frankj. Some of this … Read More. The Franki pile, known and used worldwide, was developed at the turn of the century by the Belgian engineer Frankignoul.

The reinforcing bars are tied by mm spirals at the pitch of 10 – 25 cm. The composite Franki pile is installed when it is difficult or not suitable to cast the pile shaft in situ. Typical Franki pile dimensions range from 0.

Franki piling system

Due to the ramming process, the concrete is in close contact with the soil and in this way a cylindrical shaft is obtained, which is resting on an enlarged base, formed to refusal in the bearing layer. The construction of each Franki Pile is molded to the ground conditions at each pile location, and can safely withstand very high compressive and tensile forces and substantial horizontal loads.

By expulsion of a dry concrete plug, the soil surrounding the pile base is improved and thus granki initial soil bearing capacity can be increased significantly. The diversity of the execution variations facilitates the individual adaptation to very different foundation soil conditions and construction site situations.

Franki Pile – Al-Saba Concrete Piles Co. Ltd.

The raked shafts are always reinforced over their whole length. It takes business acumen, customer service excellence, team-building skills, and a whole lot more. A special concrete bucket is used to pour a certain amount of nearly dry concrete into the bottom of the driving tube. The hammer displaces the concrete laterally into the soil previously compressed by the driving of the tube.

In addition, the pile is also suitable for the pil of tensile loads due to its feanki base.

It requires only a minimum of site preparation and in some particular cases, e. Successive charges of zero slump concrete are rammed into the soil, simultaneously withdrawing the tube. Introduction For construction programmes to be compressed into the shortest possible time to meet client handover deadlines is not unusual, but for contractors to offer innovative improvements to design to realise cost frankki time savings is far more so — particularly when this increases the pressure on the contractor to perform!

Both vertical piles and inclined piles can be executed tilted up to 4: As Managing Director Errol Braithwaite says: Alternatively, the steel casing can be installed by “top-driving”, using ordinary drop hammers.

An octagonal or circular pile, made of precast reinforced concrete or pre stressed concrete, is sunk into the tube and securely anchored on the base by means of some blows the hammer. Retrieved from ” https: This negative friction is sometimes encountered in non-compressible soils. For piles subject to uplift forces, the reinforcement is anchored in the pild base, thus providing high pull-out resistance. The pile shaft can also be made of “wet concrete”, which speeds up the construction process.

This method can be applied to different site conditions and is still widely used [2] [3] [4] due to its high tensile load capacity, and relatively low noise and ground vibration levels.

The concrete of the shaft is compacted using the drop hammer, the diameter of which is smaller than that of the reinforcement. Enlarged “Franki” base When the tube has been driven to the required depth, the casing is very slightly raised and maintained in position with the aid of steel cables. The use of this product in the building industry for over years is due to its sophisticated technology, the high standards of execution and the outstanding economic viability.

The Franki pile may be vertical or raked and its bearing capacity varies with the diameter of the pile base and the driving tube being used, which can be changed to suitable loads specified. It is interesting that in both the below marine projects, one of the common themes is great teamwork … Read More.

For Keller company, Franki Africa, which is in the process of doing the geotechnical work, this prestigious project has been somewhat of a milestone. The old adage that building roads and bridges is fundamental to the growth of an economy has certainly been heeded by the Saldanha IDZ Industrial Development Zonewhich, in contrast to many areas in South Africa, has been undertaking significant infrastructural development with the funds they have received from the Western Cape government for that specific purpose.

One such project was the recently completed construction of a m-long quay wall with a draft of
